How Nuclear Technology and Radioisotopes Are Used in Airport Security and Screening

(_77^192)Ir→(_-1^0)β+(_78^192)Pt

How and Why These Radioisotopes are Used

Ir-192 releases gamma rays which are used to examine hard to reach or hard to see places via radiography.

Cf-252 emits neutrons which we can effect other atoms. Depending on how the atoms react to the neutrons, we can tell what they are. With this technique, workers in airports can tell if nitrogen, an ingredient in explosives, is in a bag without actually opening it.

who is this, have fun citing:? i will finish this

Iridium-192

Iridium-192 undergoes beta decay and gamma emission.

Iridium is a silvery-white metal

The Nuclear Reactions Involved

Two radioisotopes are commonly used for airport security:

Iridium -192

and

Californium - 252

Half-Life of the Element

and Decay Reaction

Why Nuclear Technology is Used

Ir-192 undergoes beta decay and gamma emission. It has a half life of about 73.83 days.

Airports must have security and screening for safety in airplanes. Radioisotopes are used to scan baggage to make sure passengers are not carrying anything dangerous onto the plane.

Cf-252 produces neutrons via spontaneous fission. It has a half-life of about 2.6 years.

Californium-252

Californium-252 undergoes

spontaneous fission.

Californium is a darker, silver metal
